Jquery form function help

I am building a form and one of the components will be a drop down menu and a text box. I would like the text box to be disabled, unless they select other from the drop down. If they select other then the text field becomes active. If they then choose another option after selecting other then the text field would go back to being disabled. This would only apply to two drop downs and two text fields on the form all other text fields on the form would not be disabled by default.

Thanks!

this one works for me
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<HTML>
<HEAD>
	<script src="jquery-1.4.2.min.js"></script>
	<script>
		$(document).ready(function(){
			$("#dp1").change(function(){
				if ( $(this).val() == "-1" )
				{
					$("#otherText").removeAttr("disabled");
				}
				else
				{
					$("#otherText").attr("disabled", "disabled");
				}
			});
		});
	</script>
</HEAD>

<BODY>
	<select id="dp1">
		<option value="1">One</option>
		<option value="2">Two</option>
		<option value="3">Three</option>
		<option value="-1">Other</option>
	</select>
	<input type="text" id="otherText" disabled/>
</BODY>
</HTML>

check this : http://jsfiddle.net/7HBUP/


<form name="formshipping">
    <select name="CUST_STATE" id="CUST_STATE"><option val="">Select One</option><option val="1">One</option></select><input id="t1" name="t1" type="text" value="" disabled="disabled" /><br>
    <select name="SHIP_STATE" id="SHIP_STATE"><option val="">Select One</option><option val="1">One</option></select><input id="t2" name="t2" type="text" value="" disabled="disabled" /><br>
</form>

Open in new window



$("#CUST_STATE").change(function() {
    if( $(this).prop("selectedIndex") == 0 ) {
        $("#t1").attr("disabled", true);
    }
    else {
        $("#t1").removeAttr("disabled");
    }
})

$("#SHIP_STATE").change(function() {
    if( $(this).prop("selectedIndex") == 0 ) {
        $("#t2").attr("disabled", true);
    }
    else {
        $("#t2").removeAttr("disabled");
    }
})

Something like this will help you:

 
<select id="myDropDown" onchange="changedIt(this)">
	<option value=1> One
	<option value=2> Two
	<option value=3> Three
	<option value="x"> Other ...
</select>
<textarea id="myTextBox"></textarea>

<script type="text/javascript">

	function changedIt(obj) {
		var state=(obj.value=="x")?1:0;
		$("#myTextBox").attr("disabled",state);
	}

</script>

Open in new window


(This example works if you ensure jQuery is included. Change the IDs as necessary, of course.

You are correct, I had the wrong path to the jquery file. How would I do this with 2 drop downs and two text boxes, 1 dropdown for each text box.

Thanks
